llvlPaox/ED `laAol-il-NE FoP. Mixmo AND KNEADING'DOUGH.

Specification forming .part of Letters Patent No. 43,145, dated July 5,1864.

To aZl 'whom it .may concern Be it known that I,.W1LLIAM WELLs,of

' Middleton, in theLV county of Essex and State .of Massachusetts, haveinvented new and useful Machine forV Mixing and Kneading Dough and I dohereby decla-re that thefollowing is ai full, clear, and exactdescription of theconstruc'tion and operation of the saine,

reference being had to the accompanyin g drawings, forming a part'ofthis specification, in which-4 f side view, of thc same. f.

Likeparts are indicated bythe Same letters in both drawings. f :f7 y

The nature of my invention consists in moying, by'an'y suitablemechanical means, a two-` Figure l is afront elevation,and- FigaV 2 isaedgedlblade orspatulalwithin i a sutalilenzesf.

sel, so as to rotate, squeeze, and outthedoughl ormaterials'to bemixedand kueaded in neara ly the same manner as they are by a knife 'or Spoonin a persons hand, wherebyI' um en- Theframeof the machine may be mad-ejof Vwood or iron, and consists of the bottom piece,

A, the table B, supported by the two Sides, C C, the. two uprights, D D,fast to the top of the table B, and the top piece, E, and center piece,F, 'uniting the tw'o uprlghts, D D, as represented in Fig. l.' Throughthe table B is a round hole of the proper diameter to rcceive the mixingand kneadingvessel G, which may be made of tin or other suitablematerials, and shaped as shown in Fig. l.

To facilitate the insertion and removal of the vessel G, thefrontportion of the table B is made removable, beingcontined in place bymeans of the buttons a a.

J is a pendent arm (the Shape of which is clearly Shown in the drawings)attached to the center ofthe top piece, E, by means of the universaljoint or links k and l. rBhe lower end of J is provided with alongitudinal slot of the suitable dimensions to receive the upper end ofthe blade or spatula H, which is held in place by means ofthe button band pin c. (See f Fig. 2.)

L is a beveled pinion turning on the axle o, whichl enters the centerpiece, F, of the'.frame, as shownin Fig.1, and engaging with pinion L isa Similar pinion,fM, fast to its horizontal axle m and turning' in aslot in the center piece, F, N. being a crank and O a handle to thesame, by means of which the pinions are `driven by hand; or a pulleymaybe substituted for thecrank and the machine maybe `driven by Steamor'other power when required.

' n is a small piu vprojecting from the arm J,

as Shown in fthe drawings, and entering a hole one Side of the center ofthe pinion L, where- ;by itis obviou's that the arm J will be carried..

round in acircle.

' The general shape and size ,of the mixing and kneading blade orspatula H are shown linthedrauings.. the lower para-i i. being di-AVVided,so that the ,datl side ot" the blade may pass withlcss resistancethrough the mixture.

An undivided blade, however,

for many -purposes will answer equally well. 1

The materials being placed in the vessel'G,

a person can perform the operation of mixing and kncading them Abysimply turning 'the crank VN,and many times fasterglas well as 'withless power, than by the usual method, to

Say nothingof the greater ueatness of keep,- i'nghands and finger-nailsaway from the dough.

As the blade H iscarred in a circle round ,the inside offt-he vessel Gwithout an axial revolution, its 4action on the mass to be mixed orkneaded .resembles that of a knife or spoon in' a persons hand,rotating, squeezing, and cutting the same until the operation iscompleted and the kneaded dough becomes conglomerated round the blade,which maybe readily removed by turning the button b.

Having thus described the nature and operation of my invention, what Iclaim as new, and desire to secure by Letters Patent, 'is-T Carryinground the blade or spatula H by any mechanical means within asuitablevessel, G, so as to rotate, squeeze, and cut the materials to be mixedor kneaded, substan tially as and for the purpose described.

WILLIAM WELLS.
